Network, Public Switched Telephone Network) Sends an IAM (Initial Address Message) message to reserve an idle trunk circuit. The called number can be learned from the video call request sent by the terminal, and the relay circuit is configured to construct a transmission channel for transmitting the voice call between the terminal on the calling side and the fixed telephone on the called side. Thereafter, after the relay circuit is reserved, the PSTN sends an ACM (address complete message) information to the MSC Server; 3. The MSC Server sends a Call Proceeding call to the terminal to process the signal to inform the terminal that the MSC Server is processing the call it is requesting;

4. The MSC Server requests the wireless access network and the terminal to allocate radio resources and access Backhaul (also called backhaul) resources for this video call. Among them, wireless resources refer to resources related to wireless air interfaces. The backhaul line resource is the transmission resource between the base station and the MSC Server.

Since this step is a prior art, where the PSTN, the radio access network, and the base station are not specifically shown, other details are not described in detail, and reference may be made to details in the video call process in the prior art.

604. The call control device sends an allocation resource indication to the media gateway, so that the media gateway allocates a transmission resource for the video call according to the allocated resource indication.

The MSC Server sends an H.248 MODIFY modification message to the MGW to instruct the MGW to allocate transmission resources for the video call. Optionally, the H.248 MODIFY modification message further carries an advertisement insertion indication.

Then, the MGW receives the H.248 MODIFY message, that is, receives the allocated resource indication sent by the MSC Server; then, the MGW allocates the transmission resource corresponding to the video call according to the allocated resource indication. In particular, the MGW can establish a communication link between itself and a terminal requesting a video call, the communication link being used to carry data in a video call.

605, the media gateway obtains an advertisement from the advertisement storage;

After receiving the H.248 MODIFY modification message, the MGW sends an advertisement acquisition request to the advertisement storage. In particular, the MGW may obtain an advertisement from the advertisement storage when receiving the H.248 MODIFY modification message carrying the advertisement insertion instruction; the MGW may also receive the normal H.248 MODIFY modification message without the advertisement insertion indication. , get ads from the ad storage by yourself. The MGW can pre-store the network address of the advertisement storage.

The advertisement stored initially in the advertisement storage may be in the form of text, image or video. At this time, the advertisement storage may convert the advertisement in text or image format into the transmission resource requirement before sending the initially stored advertisement to the MGW. The advertisement of the video format; or after the MGW receives the advertisement initially stored in the advertisement storage, the MGW converts the advertisement in text or image format into an advertisement in a video format conforming to the transmission resource requirement.

606, the advertisement storage sends the advertisement to the media gateway;

After the ad store receives the ad access request sent by the MGW, the ad store sends the ad to the ad.

MGW. Specifically, when the advertisement storage sends the advertisement to the MGW, the advertisement to be sent to the MGW may be selected according to the advertisement requirement information of the advertisement, for example, the advertisement memory query meets the current time and the delivery time requirement in the delivery requirement information indicates The advertisement of the time, and then the advertised advertisement is sent to the MGW.

607: Before the video call is connected, the media gateway sends the advertisement to the terminal by using the allocated transmission resource.

After the MGW allocates transmission resources for the video call, the video call is not yet connected, and the MGW will get the obtained advertisement. At least one of the ones is transmitted to the terminal using the allocated transmission resource. At this point, the video is displayed on the video call interface of the terminal.

608. The media gateway receives the ringing data, and sends the ringing data to the terminal when the advertisement includes the voice. After the MGW allocates the transmission resource, the MGW also receives the ringing data before the video call is not connected. The process of receiving the ringing data by the MGW includes the following steps:

1. The MSC Server sends an Alerting ringing message to the terminal.

2. The ringing data is transmitted to the MGW from the relay circuit reserved by the PSTN. Usually, the MGW needs to forward the ringing data to the terminal, or generate a ringing data itself to send to the terminal. However, in this embodiment, when the advertisement sent by the MGW to the terminal includes voice, the MGW does not send the ringing data to the terminal, so as to prevent the ringing data from interfering with the voice portion in the advertisement. This step is equally applicable in other embodiments and will not be described again.

609. After the video call is connected, the call control device sends a control indication for switching the video call to the voice call to stop the advertisement.

The process of connecting a video call includes the following steps:

1. When the fixed telephone on the called side picks up the phone, the PSTN sends an ANM (Answer Message) to the MSC Server, indicating that the video call is connected.

2. The MSC Server sends a Connect connection message to the terminal, indicating that the fixed telephone on the called side is connected to the telephone. Meanwhile, if the MGW sends the ringing data to the terminal in step 608, the MSC Server also needs to simultaneously instruct the MGW to stop sending the ringing data;

3. The terminal responds to the MSC Server with a Connection Acknowledge connection confirmation message, indicating that the video call is connected. Since at 601, the user is requesting a voice call. To this end, after the video call is connected, the MSC Server may send an H.248 MODIFY modification message to the terminal, instructing the terminal to switch the video call to a general voice call, so that the terminal does not continue to insert the video advertisement during the call. After that, the MSC Server can receive the Modify Complete modification complete message of the terminal, indicating that the modification is completed.

609 can be selected and executed by the MSC Server. If the MSC Server does not execute 609, the following 610 can also be performed. That is, the MSC Server can select one of 609 and 610 for execution.

610. After the video call is connected, the call control device sends a control indication to the media gateway to stop sending the voice part of the advertisement to the terminal, so as to stop the voice part in the advertisement;

The MSC Server sends an H.248 MODIFY modification message to the MGW instructing the MGW to stop transmitting the voice portion of the advertisement. At this point, the terminal can talk normally and display a video advertisement without sound.

After 609 or 610, the MSC Serve may also request the radio access network and the terminal to modify the corresponding radio resources and back. Route line resources.

611. After the video call is hung up, send a control instruction to the media gateway to stop sending the advertisement to the terminal, so as to stop all parts of the advertisement.

If the call control device performs 610 instead of 609, the call control device may also execute 611 after 610.

The process of hanging up a video call includes the following steps:

1. When the fixed telephone on the called side hangs up, the PSTN sends a REL (Release Message) message to the MSC Server to release the relay circuit;

2. The MSC Server sends a Disconnect disconnect message to the terminal, indicating that the terminal call has been disconnected;

3. The MSC Server sends an RLC (Release Complete Message) message to the PSTN, indicating that the remote end of the relay circuit has been released.

4. The terminal replies to the Release Release message to the MSC Server.

5. The MSC Server replies to the terminal with a Release Complete release completion message;

6. The MSC Server requests the radio access network and the terminal to release the corresponding radio resource and backhaul transmission resource. After receiving the REL message, the MSC Server needs to send a control indication to the MGW for releasing the transmission resource allocated for the video call. After the transmission resource allocated for the video call is released, the MGW stops transmitting the advertisement to the terminal. That is, the MSC Server sends a control indication to the MGW to stop sending the advertisement to the terminal to stop all parts of the advertisement.

At this point, the video advertisement displayed by the terminal ends.

It should be noted that the process of connecting the video call, the process of receiving the ringing data, and the process of hang up the video call are all prior art, wherein the PSTN, the radio access network, and the base station are not specifically shown, and others are not specifically shown. For a detailed description, refer to the details of the video call process in the prior art.

It should be noted that this embodiment may also be implemented by the call control device being a CSCF, the media gateway being an IMS MGW, and the terminal being a terminal on the called side, and is not limited to the above embodiment. The related implementation details are easily considered by those skilled in the art in combination with the present embodiment, and will not be further described.

In summary, the advertisement insertion method provided in this embodiment solves the problem that the media gateway uses the transmission resource of the video call to send an advertisement to the terminal by the call control device after the call request is turned on until the call is connected. When the mobile terminal requests data in a specific server in the Internet, the problem of advertisement insertion can be realized; when the terminal does not access the data in the server in the Internet, the advertisement can be realized only when the voice call service or the video call service is used. The effect of the insertion. In addition, to the terminal or media after the video call is connected by the call control device The gateway sends a control indication so that the advertisement can stop inserting at an appropriate timing, and the effect of inserting an advertisement on the terminal without affecting the user's call process is achieved. Since the video call request sent by the terminal to the call control device may also be a normal video call request, the process of the media gateway acquiring the advertisement from the advertisement storage may also be performed in advance. To do so, please continue to refer to the following examples:

Please refer to FIG. 7, which is a flowchart of a method for inserting an advertisement according to another embodiment of the present invention. In this embodiment, the advertisement insertion method is applied to the call control device that is CSCF#1, the media gateway is the IMS MGW, the terminal is the terminal on the calling side, and the called end is the other terminal located in the CSCF#2 (both It is not specifically shown) for illustration. The method of inserting the advertisement includes:

701. The media gateway obtains an advertisement in advance from the advertisement storage, and stores the advertisement.

The IMS MGW may obtain at least one advertisement in advance from the advertisement storage and store the at least one advertisement locally. The advertisement stored initially in the advertisement storage may be in the form of text, image or video. At this time, the advertisement storage may convert the advertisement in text or image format into the transmission resource before sending the initially stored advertisement to the IMS MGW. The advertisement of the requested video format; or after the IMS MGW receives the advertisement initially stored in the advertisement storage, the IMS MGW converts the advertisement in text or image format into an advertisement conforming to the video format required by the transmission resource.

In addition, when the advertisement storage sends the advertisement to the IMS MGW, the advertisement to be sent to the IMS MGW may be selected according to the advertisement requirement information of the advertisement. For example, the advertisement storage may be based on the number of delivery times and the delivery time section in the delivery requirement information of the advertisement. Select the ad that will be sent to the IMS MGW.

702. The terminal sends a video call request to the call control device.

When the user calls the terminal on the called side to make a video call, the user can initiate a video call request to the terminal used by the user. For example, the user uses the keyboard on the terminal to dial the phone number of the terminal on the called side, and then the terminal used by the user can The video call request is sent to its pre-registered CSCF #1. The video call request is usually an INVITE invite message, and the SDP (Session Description Protocol) parameter in the INVITE invite message indicates the video media and the voice media to indicate that the video call request is included (if the SDP parameter only includes the voice media) Indicates a voice call request). Optionally, the terminal may modify the message structure of the INVITE invite message to carry the advertisement insertion indication. CSCF#1 receives the INVITE invite message sent by the terminal.

703. The call control device is a call establishment process for starting a video call by the terminal.

CSCF#1 can initiate a call establishment process for a video call for the terminal, and the call establishment process can include the following steps: 1. The CSCF#1 registered by the terminal on the calling side sends an INVITE invite message to the CSCF#2 registered by the terminal on the called side (the called terminal and the CSCF#2 are not shown), and only the INVITE invite message is included in the INVITE invite message. Can contain parameters for voice media, not video media parameters.

2. The terminal on the calling side and the terminal on the called side perform media negotiation through CSCF#1, CSCF#2 registered by them respectively. It should be noted that, in step 1, the INVTIE message may not include any media parameters, and media negotiation is performed between the terminal on the calling side and the terminal on the called side through the process included in this step. The media parameters provided by the terminal on the calling side include video media and voice media.

3. Through PCC (Policy and Charging Control), CSCF#1 triggers the establishment of the bearer by the PGW or GGSN to support the transmission of video media and voice media. Since the two media use different QoS, in this step, it may be necessary to use two different bearers to transmit video media and voice media.

Since this step is a prior art, the terminal on the called side, the CSCF #2 and the PCC, etc. are not specifically shown. For other details that are not described in detail, reference may be made to the details in the video call process in the prior art.

704. The call control device sends an allocation resource indication to the media gateway, so that the media gateway allocates a transmission resource for the video call according to the allocated resource indication.

CSCF#1 sends a MODIFY modification message to the IMS MGW, instructing the media gateway to allocate transmission resources to the video call. Since there is no direct interface between CSCF#1 and the IMS MGW, this message can be forwarded through the MGCF (Media Gateway Control Function) in the IMS. Optionally, the MODIFY modification message carries an advertisement insertion indication.

It should be added that when two terminals in the IMS make a call, their media planes can be direct communication. However, in this embodiment, if two terminals can communicate directly, CSCF #1 needs to insert the IMS MGW into the media path communicated between the two terminals. That is, after the address information (IP address, port number, protocol type) of the media plane provided by the called terminal is sent to CSCF#1 through CSCF#2, CSCF#1 replaces it with the address information of the IMS MGW and sends it to the calling terminal. Similarly, after the address information (IP address, port number, protocol type) of the media plane provided by the calling terminal is sent to CSCF#1, CSCF#1 replaces it with another address information of the IMS MGW and sends it to the called party. terminal.

705. Before the video call is connected, the media gateway sends the advertisement to the terminal by using the allocated transmission resource.

The IMS MGW sends the stored advertisement to the terminal using the allocated transmission resource. At this point, the ad starts to appear on the video call interface of the terminal.

706. The media gateway receives the ringing data, and does not send the ringing data to the terminal when the advertisement includes the voice; after the IMS MGW allocates the transmission resource, before the video call is not connected, the IMS MGW also receives the ringing data. The process of receiving ringing data by the IMS MGW may include:

1. The related media may be negotiated again according to the resource status actually allocated by the terminal on the calling side and the terminal on the called side.

2. CSCF#2 sends a 183 Ringing ringing message to CSCF#1, indicating that the terminal resource on the called side is ready and has been ringed.

3. CSCF#1 forwards the 183 Ringing ringing message to the terminal on the calling side.

4. The ringing data is uploaded from the terminal on the called side.

Generally, the IMS MGW needs to forward the ringing data to the terminal on the calling side, or generate a ringing data to the terminal on the calling side. However, in this embodiment, when the IMS MGW is to the terminal on the calling side, When the transmitted advertisement contains voice, the IMS MGW does not send the ringing data to the terminal on the calling side, so as to prevent the voice part and the ringing data in the advertisement from interfering with each other.

707. After the video call is connected, the call control device sends a control indication to the media gateway to stop sending the advertisement to the terminal, so as to stop the advertisement;

The process of connecting a video call includes the following steps:

1. When the terminal on the called side picks up the phone, CSCF#2 registered by the terminal on the called side sends a 200 OK message to CSCF#1 indicating that the video call is connected;

2. The CSCF#1 sends a 200 OK message to the terminal, indicating that the terminal on the called side has connected the video call; if the IMS MGW sends the ringing data to the terminal in step 706, the Ij CSCF#1 also needs to indicate the IMS MGW at the same time. Stop sending ringing data.

3. The terminal on the calling side responds to the CSCF #1 with an ACK acknowledgement message;

4. CSCF#1 sends an ACK acknowledgement message to CSCF#2;

5. The video call communication is performed between the terminal on the calling side and the terminal on the called side.

Since the user requests a video call in 701, after CSCF#1 sends a 200 OK message to the terminal, CSCF#1 sends a control indication to the IMS MGW to stop sending the advertisement to the terminal to stop the advertisement. At this point, the user can have a normal video call without being disturbed by the advertisement.

708. After the video call is hung up, the call control device instructs the media gateway to release the allocated transmission resource.

The process of hanging up a video call includes the following steps:

1. The terminal on the called side hangs up the call, and CSCF#2 sends a BYE release message to CSCF#1.

2. CSCF#1 sends a BYE release message to the terminal on the calling side;

3. The terminal on the calling side responds to the 200 OK message to CSCF#1; 4. CSCF#1 responds to the 200 01^ message. 3. ? #2;

5. CSCF#1 triggers the PGW or GGSN to delete or modify the bearer through the PCC.

After the video call hangs up, CSCF #1 instructs the IMS MGW to release the transmission resources allocated for the video call.

It should be noted that the process of connecting the video call, the process of receiving the ringing data, and the process of hang up the video call are all prior art, wherein the terminal on the called side, CSCF #2 and PCC, etc. are not specifically shown. For other details, please refer to the details of the video call process in the prior art.

It should be noted that the embodiment may be implemented by the MSC server, the media gateway is the MGW, and the terminal is the terminal on the called side, and is not limited to the foregoing embodiment. Relevant implementation details, which are easily considered by those skilled in the art in combination with the present embodiment, will not be described one by one.

In summary, the advertisement insertion method provided in this embodiment, after the call request and before the call is connected, the call control device instructs the media gateway to use the transmission resource of the video call to send an advertisement to the terminal, which solves the prior art only when moving. When the terminal requests data in a specific server in the Internet, the problem of advertisement insertion can be realized; when the terminal does not access the data in the server in the Internet, and only the video call service is used, the effect of the advertisement insertion can be achieved. In addition, the call control device sends a control indication to the terminal or the media gateway after the video call is connected, so that the advertisement can be stopped at an appropriate timing, and the effect of inserting the advertisement on the terminal without affecting the user's call process is achieved. . In the above embodiment, the advertisement insertion process is mainly performed by the media gateway. When the ad insertion process is mainly done by the ad storage, please refer to the following example:

Please refer to FIG. 8, which is a flowchart of a method for inserting an advertisement according to an embodiment of the present invention. This embodiment is mainly described by using the advertisement insertion method to the call control device shown in FIG. The ad insertion method includes:

801. Receive a call request sent by the terminal on the calling side, or send a call request to the terminal on the called side. In a call, there are both the terminal on the calling side and the terminal on the called side.

If the terminal managed by the call control device is the terminal at the calling side, the call control device may receive a call request sent by the terminal, and the call request may be a voice call request or a video call request. The call request optionally carries an advertisement insertion indication.

If the terminal managed by the call control device is the terminal on the called side, the call control device may send a call request to the terminal, and the call request may be a voice call request or a video call request.

It should be noted that, in order to simplify the description, the terminal managed by the call control device is mainly referred to as the calling side in this document. For the description of the terminal, the implementation of the terminal managed by the call control device is the terminal on the called side, which is easily understood by those skilled in the art, and will not be further described.

When the terminal managed by the call control device is the terminal on the calling side, after receiving the call request of the terminal, the call control device may initiate a call establishment process of the voice call or the video call for the terminal.

802. Before the call is connected, send a first indication carrying the identifier information of the terminal to the advertisement storage, to instruct the advertisement storage to send an advertisement to the terminal according to the identification information.

The call control device may also send a first indication carrying the identification information of the terminal to the advertisement storage device during the call establishment process for starting the voice call or the video call for the terminal, to instruct the advertisement storage to send the advertisement to the terminal according to the identification information. The call control device may obtain the identification information of the terminal from the call request, or may interact with a management network element such as a PGW (PDN Gateway) to obtain the identification information of the terminal. The identification information of the terminal is usually the IP address of the terminal in the packet switching network; when the advertisement storage sends an advertisement to the terminal, the advertisement can be sent to the terminal by using the packet switching network according to the IP address of the terminal. In other words, after receiving the first indication, the advertisement storage may use the identification information of the terminal, and use the PDP Context (Packet Data Protocol Context) that has been established by the advertisement utilization terminal and the terminal data protocol Context that has been allocated to the terminal. The IP address is sent to the terminal. The advertisement may be text, image or video, etc., preferably a video.

It should be noted that the identifier information of the terminal may also be an IMSI (International Mobile Subscriber Identification Number) or an MSISDN (Mobile Station ISDN). At this point, the terminal can register with the ad storage in advance, and the registration process is as follows:

First, the advertisement memory receiving terminal uses an IMSI or MSISDN sent by the packet switching network;

Then, the advertisement storage associates the IMSI or MSISDN of the terminal with the IP address of the terminal in the packet switching network, and the IP address of the terminal can be known in the communication process in the previous step;

Then, if the advertisement memory receives the first indication of the call control device, and the identifier information of the terminal carried by the first indication is an IMSI or an MSISDN, the advertisement memory searches for the IP address of the terminal in the packet switched network according to the pre-stored association relationship; An advertisement is sent to the terminal using a packet switched network based on the found IP address.

In summary, the advertisement insertion method provided in this embodiment solves the problem that the prior art transmits only the advertisement to the terminal by the call control device after the call request is turned on until the call is connected. When the data in a specific server is used, the problem of advertisement insertion can be realized. When the terminal does not access the data in the server in the Internet, the effect of the advertisement insertion can also be achieved when only the voice call service or the video call service is used. In addition, compared with the foregoing embodiment, the embodiment inserts advertisements through the advertisement storage and the PS domain, and may not occupy the signaling and processing resources of the media gateway, and does not need to use the transmission resources of the video call to perform advertisement insertion. In. Please refer to FIG. 9, which is a flowchart of a method for inserting an advertisement according to another embodiment of the present invention. This embodiment is mainly illustrated by applying the advertisement insertion method to the advertisement memory shown in FIG. 1. The method of inserting the advertisement includes:

901: Receive a first indication sent by the call control device, where the first indication is an indication that the call control device carries the identifier information of the terminal after the call is sent or received, and before the call is connected. The advertisement store may receive the first indication sent by the call control device, where the first indication carries the identifier information of the terminal. The identification information of the terminal is usually an IP address, or it may be IMSI or MSISDN.

902. Send an advertisement to the terminal according to the identification information.

The advertisement storage can find the terminal through the identification information of the terminal, and then send the advertisement to the terminal through the PDP Context pre-established by the terminal in the PS domain and the IP address already allocated to the terminal.

It should be noted that, if the identification information of the terminal is an IP address, the advertisement storage may directly find the terminal according to the IP address of the terminal, and send an advertisement to the terminal; if the identification information of the terminal is an IMSI or an MSISDN, the advertisement The memory finds the IP address of the terminal in the packet switched network according to the pre-stored association relationship; and then uses the packet switched network to send an advertisement to the terminal according to the found IP address. The pre-stored association relationship may be an association relationship generated when the terminal registers with the advertisement memory in advance, and the registration process may be as follows:

Then, the advertisement memory associates the IMSI or MSISDN of the terminal with the IP address of the terminal in the packet switched network, and the IP address of the terminal can be known during the communication process in the previous step.

In summary, the advertisement insertion method provided in this embodiment solves the problem that the prior art transmits only the advertisement to the terminal by the call control device after the call request is turned on until the call is connected. When the data in a specific server is used, the problem of advertisement insertion can be realized. When the terminal does not access the data in the server in the Internet, the effect of the advertisement insertion can also be achieved when only the voice call service or the video call service is used. In addition, compared with the foregoing embodiment, the present embodiment performs advertisement insertion through the advertisement storage and the PS domain, and may not occupy the signaling and processing resources of the media gateway, and does not need to perform advertisement insertion by using the transmission resource of the video call. Please refer to FIG. 10, which is a flowchart of a method for inserting an advertisement according to another embodiment of the present invention. In this embodiment, the advertisement insertion method is mainly applied to the MSC, the device on the calling side of the terminal, and the opposite end of the called side are fixed telephones. The MSC may include an MSC Server and an MGW, and is sometimes called It is MSC/VLR (Visitor Location Register). The method of inserting the advertisement includes:

1001, the terminal registers with the advertisement storage;

The terminal can establish a PDP Context in the PS domain and obtain an IP address. It is then registered with the ad store so that the ad store can be connected to the terminal. During the registration process, the terminal can register using the IP address, IMSI or MSISDN as the identification information. The terminal can obtain the address information of the advertisement storage in advance through a DNS (Domain Name System) setting, an OTA (Over the Air Technology) or a DM (Device Management) technology.

The registration process can be as follows:

1002. The call control device receives a call request of the terminal.

The MSC can receive a voice call request or a video call request of the terminal. For example, the terminal decides to make a voice call to a fixed telephone number, and the terminal sends a Setup message to the previously registered MSC. Optionally, the Setup message further includes one or more of an IP address of the advertisement storage, an IP address of the terminal, an IMSI of the terminal, and an MSISDN.

After receiving the call request of the terminal, the MSC may initiate a call establishment process for the terminal.

The call establishment process may include the following steps:

1. The MSC analyzes the called number as a fixed telephone number, and sends an IAM (Initial Address Message) information to the PSTN (Public Switched Telephone Network) to reserve an idle relay circuit. . The called number can be learned from the call request sent by the terminal, and the relay circuit is used to construct a transmission channel for transmitting a voice call between the terminal on the calling side and the fixed line on the called side. Thereafter, the PSTN sends an ACM (address complete message) message to the MSC Server after the relay circuit reserves the reservation;

2. The MSC sends a Call Proceeding call to the terminal to process the signal to inform the terminal that the MSC is processing the call it is requesting;

3. The MSC requests the wireless access network and the terminal to allocate radio resources and access Backhaul (also called backhaul) resources for this call. Among them, wireless resources refer to resources related to wireless air interfaces. The backhaul line resource is the transmission resource between the base station and the MSC.

The present step is a prior art, and the PSTN, the radio access network, and the base station are not specifically shown. For other details, refer to the details in the prior art during the call; 1003: Before the call is connected, the call control device sends a first indication carrying the identifier information of the terminal to the advertisement storage, instructing the advertisement storage to send an advertisement to the terminal;

While the MSC initiates the call setup process for the terminal, the MSC sends a first indication carrying the identification information of the terminal to the advertisement storage, instructing the advertisement storage to send an advertisement to the terminal. The identification information of the terminal can be an IP address, IMSI or MSISDN.

It should be noted that if the identification information of the terminal is an IP address, 1001 is an optional part.

1004. The advertisement storage receives the first indication, and sends an advertisement to the terminal according to the identifier information in the first indication. After receiving the indication, the advertisement storage may use the identifier information of the terminal to use the PDP Context that the advertisement has established by the terminal. And the IP address that has been assigned to the terminal is sent to the terminal. The advertisement may be text, image or video, etc., preferably a video.

It can be seen from the advertisement storage method shown in FIG. 2 that the advertisement storage can receive delivery request information of each advertisement sent by the advertisement policy and the charging controller, and the delivery request information includes a delivery time section and a delivery area. To this end, when the advertisement storage device sends the advertisement to the terminal, the advertisement to be sent to the terminal can be selected according to the advertisement request information of the advertisement. Specifically, this step can include:

1. Querying the advertisement that meets the delivery requirement information, and the information conforming to the delivery requirement includes: the current time meets the time indicated by the delivery time section, and/or, the area where the terminal is located conforms to the delivery area, and the area where the terminal is located is identified by the terminal The information is determined; determining the area in which the terminal is located according to the identification information of the terminal may be performed by, but not limited to, location location service such as LBS (Location Based Service).

2. Send an advertisement to the terminal according to the identification information to query the information that meets the delivery requirement information.

Thereafter, the terminal can receive the advertisement sent by the advertisement memory and then start playing the advertisement on its own screen.

1005, after the call is connected, the call control device sends a second indication to the advertisement storage to stop sending the voice part of the advertisement or the advertisement to the terminal;

The process of connecting the call may include the following steps:

1. When the fixed telephone on the called side picks up the phone, the PSTN sends an ANM (Answer Message) to the MSC, indicating that the call is connected;

2. The MSC sends a Connect connection message to the terminal, indicating that the fixed telephone on the called side is connected to the telephone;

3. The terminal responds to the MSC with a Connection Acknowledge connection confirmation message, indicating that the call is connected.

After the call is connected, if the terminal requests a voice call, the MSC decides not to insert an advertisement, or the terminal requests a video call, the MSC may send a stop to the advertisement memory to send the advertisement to the terminal after the call is connected. The second indication to stop the advertisement. If the terminal requests a voice call and the MSC decides to continue inserting the advertisement, the MSC may also send a second indication to the advertisement memory to stop transmitting the voice portion of the advertisement to the terminal, so as to stop the voice portion of the advertisement and avoid the voice portion of the advertisement. Interference with voice calls.

1006. After the call hangs up, the call control device sends a second indication to the advertisement store to stop sending all portions of the advertisement to the terminal to stop all portions of the advertisement.

The process of hanging up the call may include the following steps:

1. When the fixed telephone on the called side hangs up, the PSTN sends a REL (Release Message) message to the MSC to release the relay circuit;
